Abstract

A product change method for a cigarette manufacturing machine, wherein an input hopper receives a first type of shredded tobacco from a supply header, and feeds it to at least one channel for forming, on a conveyor, a bead of tobacco, which is released onto a paper strip travelling along a forming table for forming a continuous cigarette rod; the method provides for cutting off supply of the first type of shredded tobacco to the header, emptying the header, cutting off communication between the header and the input hopper, cutting off supply of the paper strip, keeping the manufacturing machine running to form a waste stream of shredded tobacco of the first type and empty the manufacturing machine, and feeding a second type of shredded tobacco through the supply header and the input hopper to fill the manufacturing machine completely before starting up supply of the paper strip.

Claims (10)

1. A method of replacing a product in a cigarette manufacturing machine in which an inlet hopper (2) receives a first type (3a) of cut tobacco from a feed collector (4) and feeds it to at least one channel (17) to form a roller (19) tobacco, which is produced on a paper strip (22) moving along the table (20) to form a continuous cigarette rod (21), comprising the steps of stopping the supply of said first type (3a) of tobacco to the production machine (1), unloading the first type (3a) cut tobacco from a production machine (1) in order to form a withdrawn stream (31) of cut tobacco of the first type (3a), and supply of the second type (3b) of cut tobacco through the feed collector (4) and the inlet hopper (2) until the production machine (1) is completely filled. 2. The method according to claim 1, in which the unloading of the first type (3A) of tobacco includes the stage of stopping the paper strip (22). 3. The method according to claim 2, comprising the additional step of starting feeding the paper strip (22) only when the production machine (1) is completely filled with cut tobacco of the second type (3b). 4. The method according to any one of claims 1 to 3, in which the tobacco of the first type (3a) is discharged by deflecting the tobacco roll (19) into the container means (31). 5. The method according to any one of claims 1 to 3, in which the first type of tobacco (3a) is discharged by deflecting the tobacco roll (19) into the container means (31) at the output end of the forming table (20). 6. The method according to any one of claims 1 to 3, in which the production machine (1) is completely filled with cut tobacco of the second type (3b) in successive batches, each load being formed inside the specified collector (4), separated from the inlet hopper (2) , and unload in the input hopper (2) by connecting the specified collector (4) to the input hopper (2). 7. The method according to any one of claims 1 to 3, in which the production machine (1) is completely filled with cut tobacco of the second type (3b) by forming a roller (19) of tobacco of the second type (3b) along the forming table (20). 8. The method according to claim 7, in which the roll (19) of tobacco of the second type (3b) is left without a corresponding paper strip (22) until the desired desired compactness is achieved. 9. The method according to claim 8, in which the second type of tobacco roll (19) (3b) without a corresponding paper strip (22) is rejected into the container means (31). 10. The method according to claim 8 or 9, in which the paper strip (22) is fed together with the second type of tobacco roll (19) (3b) along the forming table (20) to form a new type of continuous cigarette core (21), wherein the initial a portion of a new type of continuous cigarette rod (21) is deflected into the container means (31).
